Hi,


I'm new to openFoam and am going through the tutorials with macOS 10.14.6. When I enter the potentialFoam Cylinder tutorial ($FOAM_TUTORIALS/basic/potentialFoam/cylinder), I run blockMesh and get the following output:

"

I suspect it's something to do with the installation from seeing similiar errors on other threads, however I can't work out what to do as I'm not running on windows or linux etc. I did the installation exactly according to the openfoam instructions with docker (https://www.openfoam.com/download/in...binary-mac.php), and when I execute docker images to check if its done right, I get the following:



"REPOSITORY TAG IMAGE ID CREATED SIZE
openfoamplus/of_v2012_centos73 release 8c2e256b99c8 2 weeks ago 1.99GB
openfoam/openfoam8-paraview56 latest be19d87c75fc 2 months ago 2.57GB
openfoam/openfoam8-graphical-apps latest c2e1cd53823d 2 months ago 1.76GB"


I think the installation is therefore okay. Hope someone can help. Thank you

Hi !

I am rather new to OpenFOAM as well but from what I understand so far, most files in OpenFOAM, I am thinking probably the tutorials files too, are locked (including all the solvers and other utilities). So to complete a tutorial and run blockMesh, the case files should be copied over in your "run" folder first.

That's what I would try anyway !

Good luck !

Hi, thank you for the reply. I tried that as well but I get the same error unfortunately . Also, what might be of interest is that I get the same error when I run blockMesh for the case 'bump2D', among some others. So the installation seems to have worked for some cases but not others.

I think the problem is that I need to download make for mac in order to be able to run the dynamic code in blockMeshDict. I have done this using homebrew but I'm not sure where to go from here as it's still not making any difference. Any a help on this one would be great!
